For one, it can be highly invasive, causing significant disruption to the surrounding environment. Additionally, as oil reservoirs are depleted over time, the yield from conventional drilling methods decreases, making it less cost - effective in the long run.

2.2 Secondary and Tertiary Recovery Methods

To address the declining yields in mature oil fields, secondary and tertiary recovery methods have been developed. Secondary recovery methods, such as water flooding, involve injecting water into the reservoir to push the remaining oil towards the production wells. Tertiary recovery methods, like enhanced oil recovery (EOR), use more advanced techniques such as injecting chemicals, gases, or heat into the reservoir. Nonetheless, these methods also have their drawbacks. They can be expensive and may have environmental impacts due to the use of chemicals or the high energy requirements for heat - based EOR methods.

3. Innovative Extraction Technologies

3.1 Nanotechnology in Oil Extraction

Nanotechnology is emerging as a promising area in natural oil extraction. Nanoparticles can be designed to have unique properties that can enhance the extraction process.
